I was just checking your specs. That pw supply is a 20pin [at least the one I found was] and the board needs a 24pin. While your manual may say this is OK, IMO you are asking for problems when you use a low end pw supply and it is a 20pin unit on a 24pin board.

Is this your pw supply?

I couldn't agree more....if I'd known this board/bios offers no way to turn off overclocking I would never have bought it.

Mine runs like a champ and I haven't had a glitch out of it since.


Ok so I think I have it, just so you can see it go here
http://support.asus.com/download/dow...us&model=A8S-X
then click on manuals to A8S-X User's Manual for English Edition (E2123) if you have the manual then go to the Advanced Menu 2.4 section in the manual and go to Jumperfree Configuration then you should see AI overclocking...I think mine may have been intially set to auto but then again I dont remember I think if you set it to standard you will be ok. I think setting it to manual brings up more things to tweak so I think standard is what you need. I am almost sure that's what I had to change. If it's set to standard initially then set it to auto. (ok I just re-read your post and it being set to auto, that almost confirms that I changed it to standard)

Let us know if this corrects the issue.

Hi - thanks for your detailed reply to my post - glad there's someone else out there with the same board that's had the same challenge that can offer advise.

Just to clarify: when you say 'standard' are you referring to 'manual mode' within the Jumperfree Configuration setting screen in BIOS? This opposed to 'auto' which is what the factory default over-clocking settings are set to.

There are lots more options that can be tweaked when in manual mode, and I have tried tweaking a few settings in there, but with no positive effect. I see no 'standard' setting in there to tweak, so if you could offer a bit more detail about what you mean by changing to standard and/or wheat exactly tweaked on your mainboard, that would be great....appreciate it.

Would be great to know precisely what you changed so I could mirror what you did, hopefully I'll get the same good results - again, many thanks.

Ahhh....very good - very helpful.. I've actually already figured out how to set to manual so I'll try setting FSB speed down a bit.

I really appreciate your inputs on this thread.

When I said 'standard' my BIOS actually has an option under the Jumperfree configuration for manual, auto and standard. What's interesting is that fact that I see 2 different manuals on the website and 1 mentions a way to set it to manual, auto, and standard and the other has only manual and auto. I wonder what the difference is in my board and yours.

[crjdriver]

Again I am betting this is NOT the source of your problem. Do you have the pw supply I linked to? If so, that is most likely the problem.

BTW I am no fan of asus boards however asus is not alone in doing this. I believe msi started doing this slight overclock a few years ago [just so they can claim their board is faster]

[dgmtoronto]

The power supply connected to tis ASUS board is definitely a 24 pin, not a 20 pin.

Is this your pw supply?

Forgot to answer your question about the power supply: my power supply is model # JPC-450, not the one you provided the link to which is the JPC-450DF.

There might be a difference in the BIOS - I checked again, and I don't have a 'standard' option - my 3 options are auto, manual and overclock profile.

The manual says there should be 4 options: auto, manual, standard and overclock profile, but there are only 3 on mine.

What version is your BIOS? I'm running v2.57. I did not find a more recent version than that available at the ASUS website when I checked the other day.

This is the last time I ever buy an ASUS-anything again. I was running an MSI board with no problems for 5 years before this. Before that I had an ASUS board and video and had problems with that setup to. ASUS must be cursed.

That is probably the same pw supply with a 24pin atx connector instead of a 20pin. The specs I found are a pretty low quality unit.

Set AI to manual and type in whatever fsb you want. As I posted, I seriously doubt that is what is causing your problems. Since it is an asus board, have you loaded asus probe? If so, what does it say about voltages?

BTW I agree I have not used an asus board for a number of years now. Still have one build here running an asus however it has not really given me any problems.

AI is set to manual, but there is no option labeled FSB available. Available options are:
CPU Frequency
PCI Express Frequency
PCI Clock Sync Mode
DDR Reference Voltage
FID/VID Change
Processor Frequency Multiplier
Processor Voltage

Thoughts?

[crjdriver]

Yes, have you read your manual completely? I posted the page that explains how to set it. Note that is the online manual; the paper one may have the info on a different page.

[crjdriver]

BTW you might want to download the online manual. Quite often things are changed after the paper manual is printed.

Ok I was smoking crack apparently, there was no standard option in my BIOS but mine is set to auto AND the overclocking profile options which gives you percentages to OC mine is set at 5%

Gotta get you off that stuff! So those are the same settings I had my BIOS set to when all the crashing was occurring.

I might be onto something else though: After doing some testing on my RAM last evening, I've gone almost 24 hours of continuous stable running. I pulled one of the sticks and am running with just 1 stick (1GB) in the B1 slot which apparently is the preferred slot on asus mboards if you're going to run with a single DIMM. Its working.

Tmrw I'll add the second DIMM back and see if original stability issues recur. Maybe something is funky with one of my DIMMs. I matched up the RAM beforehand with the specs on this asus mboard and its supposed to be fully compatible. I don't know enough about this stuff to understand why RAM would cause the stability issues I've been experiencing. Insights on that welcomed from anyone with more knowledge than I've got.

Thanks again for the posts and advice on all this.
